Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you string together 8 glucoses, how many water molecules will come out?
A
1
B
4
C
7
D
8
Explanation: 

Detailed explanation-1: -For each molecule of glucose produced: 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction.

Detailed explanation-2: -Okay, so if we are linking together 100 glucose molecules to make the polymer there will be 99 water molecules, and that would be our final answer.

Detailed explanation-3: -Five molecules of water are produced from this reaction. Monomers are joined through condensation reactions (in this case, a dehydration condensation reaction). Water is a product of the reaction; one water is produced for every bond that is formed. Therefore, six adjoined monomers release five molecules of water.

Detailed explanation-4: -Answer and Explanation: It would require nine water molecules to break down an oligosaccharide containing 10 glucose units. Such an oligosaccharide would contain nine glycosidic linkages, one between each pair of adjacent carbohydrate subunits in the polymeric molecule.
